It's much like the Shadowrun SIN system. Anyone who was SIN-less basically didn't exist in the Shadowrun world. It meant you couldn't get housing, reliable work, food, or medicine. Basically, you were a nobody and everyone made sure you knew it. Similarly, mailing addresses have had similar effects in society and now not having a permanent digital presence will become another barrier to block people who found themselves not able to setup such a presence in the past or can't even afford to get online with a cheap phone. All because the corps demand a means to uniformly know who you are beyond your name.
